“After [FC Bayern München’s] Thomas Müller, Sandro was the most prolific German forward in the Bundesliga last season,” said Hoffenheim’s sporting director Alexander Rosen. “We are committed to signing strong and charismatic players. In Wagner, we have somebody with a huge presence both on and off the field.”

Wagner, who stands 1.94 metres tall, plundered 14 goals and four assists in the Bundesliga last season as promoted , five points clear of the automatic relegation places – and one ahead of Hoffenheim.

'Combative and strong'

"Wagner is a combative and strong striker,” said Hoffenheim head coach Julian Nagelsmann. “He not only has excellent finishing, but he can also be well integrated into the build-up play and works hard when the opposition has the ball.”
